Question

A diver is working 10 feet below the surface of the water. The gap between the water and the deck of his support barge is 1/8 of the total length of air hose, and 2/3 of the total length remains on the reel. What is his maximum working depth without a change of equipment?

Answer 1

1/8 L + 10feet=1/3 L
solve for L.

Then working depth is 10 feet less.
